Which best describes uniformitarianism?

• The formation of rock layers has slowed because humans have altered the environment.

• The movement of the continents no longer occurs because of changes in ocean currents.

• The time it takes for erosion to occur has changed since Earth first formed.

A certain fossil (Y) is found in a layer of rock that lies between two index fossils, X and Z. Surprisingly, the older of the index fossils (Z) is found above the other fossils, suggesting that the rock layer has overturned. Which dating method is BEST to confirm the rock layer has overturned by determining the ages of these fossils?

• anatomical comparison

• gene sequencing

• radiometric analysis

• fossil depth measurement

Scientists can use relative dating, absolute dating, or a combination of the two techniques to determine the age of a fossil.  Which of the following could be determined using both methods?

• the exact age of a fossil

• which of the two fossils is older

• a narrow age range for a fossil

• the difference in age between two fossils

A geologist identifies the identical index fossils in rock layers from two different areas.  Which conclusion is best supported by this discovery?

 

• The deposition rate of the two rock layers was identical.

• The two rock layers were deposited at approximately the same time.

• The index fossil will also occur in sediment deposited on top of these rock layers.

• The fossil organism evolved independently in the two separate areas.
